摘要

本研究探讨了耦合变系数四阶非线性薛定谔方程的高阶局域波，该方程用于描述光脉冲在非均质光纤中的同时传播。在种子解和拉克斯对的基础上，构建了 N 次阶局部波解。通过数值模拟，对流氓波与暗-亮孤子的相互作用进行了图解分析。这些结果有助于研究非线性光学中的局域波现象。

Localized wave solutions to coupled variable-coefficient fourth-order nonlinear Schrödinger equations

This study investigates higher-order localized waves for coupled variable-coefficient fourth-order nonlinear Schrödinger equations, which are used to describe the simultaneous propagation of optical pulses in an inhomogeneous optical fiber. Based on the seed solutions and Lax pair, the Nth-order localized wave solutions are constructed. The interactions of rogue waves with dark–bright solitons are graphically analyzed via numerical simulation. The results are helpful for studying localized wave phenomena in nonlinear optics.
